塔河4区碳酸盐岩缝洞型油藏周期注水实践及认识

塔河4区奥陶系油藏是以发育大规模溶洞为主的碳酸盐岩缝洞型油藏,2005年开展注水开发以来,稳定见效期5-6年。2011年开始注水效果变差,注采井组水窜严重,递减明显加大。本文针对注水效果变差的现状,从周期注水机理入手,总结了周期注水参数优化、不同缝洞及注采连通关系周期注水方法,周期注水有效改善了区块开发效果。

Indigenous Peoples’ Health Care: New approaches to contracting and accountability at the public administration frontier

Abstract

This article analyses reforms to contracting and accountability for indigenous primary health care organizations in Canada, New Zealand, and Australia. The reforms are presented as comparative case studies, the common reform features identified and their implications analysed.

The reforms share important characteristics. Each proceeds from implicit recognition that indigenous organizations are ‘co-principals’ rather than simply agents in their relationship with government funders and regulators. There is a common tendency towards more relational forms of contracting; and tentative attempts to reconceptualize accountability. These ‘frontier’ cases have broad implications for social service contracting.

关于我国推行住房抵押贷款证券化的对策分析

住房抵押贷款证券化是我国未来住房金融发展的必然方向，为了在我国顺利推行住房抵押贷款证券化。应加强培育住房抵押贷款一级市场与投资者，完善相关的法律法规，完善信用评级制度，完善相关的会计和税收制度等。     

经济周期定期方法与研究进展

经济波动一直是宏观经济分析与预测中的经典问题,而经济周期拐点的及时识别对政府前瞻性经济政策的制定和企业投资经营战略的调整具有重要意义。鉴于我国目前尚没有权威机构对经济周期进行实时监测和发布,因而在划分经济周期和拐点识别时,往往局限于一种方法,不同方法有效性的比较缺乏一个基准参考。文章对国内外研究经济周期及其周期拐点定期的方法进行梳理和分析,依据经济周期定期方法的研究脉络,对主流的方法进行评述,并对我国经济周期定期进行展望,希望能在分析中国宏观经济波动特征和经济走势预测方面提供一些方法论参考和借鉴。     

Environmental impacts of changes to healthier diets in Europe

Food consumption causes, together with mobility, shelter and the use of electrical products, most life cycle impacts of consumption. Meat and dairy are among the highest contributors to environmental impacts from food consumption. A healthier diet might have less environmental impacts. Using the E3IOT environmentally extended input output database developed in an EU study on Environmental Impacts of Products (EIPRO), this paper estimates the difference in impacts between the European status quo and three simulated diet baskets, i.e. a pattern according to universal dietary recommendations, the same pattern with reduced meat consumption, and a ‘Mediterranean’ pattern with reduced meat consumption. Production technologies, protein and energy intake were kept constant. Though this implies just moderate dietary shifts, impact reductions of up to 8% were possible in reduced meat scenarios. The slightly changed food costs do not lead to significant first order rebound effects. Second order rebounds were estimated by applying the CAPRI partial equilibrium model. This analysis showed that European meat production sector will most likely respond by higher exports to compensate for losses on the domestic meat market. Higher impact reductions probably would need more drastic diet changes.     

循环经济模式下的企业生产组织研究

提出了在循环经济规则下,企业生产责任从产品生产,产品销售和售后服务向着产品的再使用,再制造,回收资源化和最终处置延伸中的产业组织的新结构与新机制。分析评价了产品寿命周期每一事件对环境产生的影响和影响程度。为实现产品寿命周期的环境负面影响最小化,认为企业必须实施清洁生产,在技术、设备和工艺流程上进行创新。为保证企业清洁生产的有效实施,提出企业必须建立ISO14001环境管理体系,在产品生产的组织和程序上落实和执行ISO14001标准,使ISO14001环境管理体系在企业产品寿命周期上为实施清洁生产,节能降耗和保护环境保驾护航。
